Thyroid function tests generally consist of 5 tests: triiodothyronine, total thyroxine, free triiodine, thyronine, free thyroxine, thyroid stimulating hormone, and anti-triiodothyronine. The cost of the test is about 150-300 RMB, and there is no standard price, but only an approximate range, because it depends on various factors, such as the level of the hospital, the city where it is located, and the method of the test. When the thyroid gland is affected by some disease or other factors, the level of hormones secreted in the blood will change accordingly, so it is possible to determine whether the function of the thyroid gland is affected by the 5 tests. The test is relatively simple and requires only a venous blood sample, which must be taken on an empty stomach to ensure the accuracy of the results. The cost of the test is directly related to the level of the hospital, the higher the level of the hospital, the higher the fee will be. If it is a first-tier city, then the fee will be higher than the second and third-tier cities. The method of examination is a key factor in determining the cost, if the enzyme-linked immunoassay costs only about 160 yuan, while if the chemiluminescence method costs about 250-300 yuan. If you have symptoms of thyroid disease, it is recommended that you have a thyroid function test, which is not very expensive overall and only takes two working days to get the results.
